Blue refabric
Blue refabric / Duck French Coverall Jacket
This piece is based on a French work jacket, crafted from duck fabric with a rugged, uneven texture and finished with a paraffin treatment infused into the fabric.
With wear, chalk marks and fading naturally develop, allowing you to enjoy its unique aging process. It is lightly water-repellent and resistant to dirt, offering both practicality and character.
Balancing a clean appearance with ease of movement, the three-panel construction creates a smart yet comfortable silhouette that never feels restrictive.

Blue refabric
Built on a concept of high-quality Japanese fabrics and a commitment to authentic craftsmanship. Originally produced for many years as a ROCOCO exclusive line of JAPAN BLUE JEANS, it relaunches in 2026 under the name “Blue refabric.” Production centers around partner factories of JAPAN BLUE JEANS. The name combines “Blue” — representing Japanese denim — with “Refabric,” a coined word blending Republic and Fabric. Inspired by the idea of a “Blue Republic,” the brand honors Japan’s textile heritage while creating garments that bring out the individuality of the wearer.
The fabric uses duck cloth with a naturally irregular texture. By omitting a lining, it is designed for wear across multiple seasons.
The paraffin finish adds light water repellency and resistance to dirt, enhancing practicality.
The paraffin coating, created by infusing wax into the fabric, develops unique aging over time, including chalk marks—where creases and folds appear lighter—and a natural fade that adds character.
Comfortable construction
The neckline is designed to open cleanly and maintain a balanced shape, whether buttoned or unbuttoned.
The shoulders feature a split raglan design—appearing as a set-in sleeve from the front and a raglan from the back—combining a structured look with ease of movement.
A basic chest pocket is placed on the left, while large patch pockets at the waist provide practical storage.
An inner pocket on the right chest adds convenience.
Structured for comfort and form
The body is constructed using a three-panel pattern (front, side, and back), creating a dimensional, clean silhouette. It offers a smart appearance while remaining comfortable and unrestricted to wear.
A label on the inside signifies production at a partner factory of JAPAN BLUE JEANS.

Staff comment
| ●Staff Height/Weight: 165cm / 64kg Wearing size: S / M Body type: Slim Fit: Just right / Relaxed Length: Just right For a true fit, I would choose size S; for layering thicker items like sweatshirts, I would go with size M. The three-panel construction creates a structured silhouette that doesn’t spread outward, giving a clean and refined look. |
| ●Staff Height/Weight: 171cm / 70kg Wearing size: M Body type: Standard Fit: Relaxed Length: Just right Size M provides a comfortable amount of room. Thanks to the split raglan construction, it maintains a structured set-in appearance while allowing surprisingly smooth arm movement. |
| ●Staff Height/Weight: 177cm / 73kg Wearing size: L Body type: Standard Fit: Relaxed Length: Just right Wearing size L. There is no tightness in the shoulders or body, and the slightly cropped length captures the distinctive balance of French workwear. |
| ●Staff Height/Weight: 181cm / 78kg Wearing size: XL Body type: Solid Fit: Relaxed Length: Just right Wearing size XL. Even with a solid build, the three-dimensional body construction prevents any tightness around the chest. The generous sleeve length is also a strong point, ensuring it works well for taller individuals without feeling short in the arms. |
